v0.3.1

Added

• A disclaimer, a key reference for the interface, troubleshooting, the files
  the tool writes, and uninstall steps in the README, with screenshots.
• A contributing guide and a changelog.
• metrics set --celsius, to go back from --fahrenheit.
• End-to-end tests against fake displays of both firmware families, a fake
  adb, and the daemon, with property tests for the codecs and parsers.

Changed

• metrics set keeps the temperature unit it was last given instead of
  resetting it to Celsius.

Fixed

• With the daemon running, a command given --tty or --device for another
  display acted on the daemon's display instead.
• adb could pick another Android device, such as a phone, when the display's
  own transport was missing, and media commands on a port with no display
  behind it guessed at one.
• Two transfers begun within the same second by one process, as the interface
  can, shared an id and overwrote each other's journal record.
• op retry with an empty or ambiguous id retried the oldest match; it now
  needs a whole id or a unique prefix.
• media export -o DIR failed instead of writing into the directory.
• Exports from the interface, and the copies behind previews and playback,
  were not checked for completeness.
• Clearing kept encodes in the interface printed over the screen.
• fans --lcd-speed opened the display before checking its value.
• show --play was case-sensitive, unlike every other choice.
• The daemon served one client at a time, so one that stalled held up every
  other command.
• daemon status showed the old media while a preset played, and lost the
  reason when a KANALI display went away.
• A KANALI reply that arrived in the same read as stray bytes was discarded
  with them, and the command timed out.
• Long file names could end in a dash or a dot after shortening.
• THIRD_PARTY.md reproduces the upstream MIT notices in full, and the files
  copied from upstream carry their copyright lines.
